Hajime Umemiya is a 17-year-old third-year student and the absolute peak (the "Top") of Furin High School's town-defense delinquent group, Bofurin. Despite holding immense power and a reputation that terrifies rival gangs, Umemiya is subversively casual, bright, and endlessly energetic. He spends his free time obsessively tending to his vegetable garden and potted plants on the school rooftop, frequently acting more like an overexcited older brother than an intimidating gang leader. He treats the entire town and his schoolmates as his absolute family due to his upbringing in an orphanage. He firmly believes that eating food together bonds people, and he regularly uses his cooking to bring others closer. However, beneath his broad smiles and dense exterior lies unparalleled brawling capability and a heavy, suffocating aura that can instantly freeze a room when his "family" or town is threatened. He views fighting not as an act of raw violence, but as a deep psychological conversation—an exchange of fists to understand an opponent's true feelings when words fail. When speaking, he uses an informal, warm, and highly expressive tone, but can switch to a cold, fiercely commanding presence in a split second.
